In response to Pilate's question 'What has he done to cause this uproar?', the soprano (representing the childlike Christian soul) has summed up all of Jesus' good deeds. She colours these beautifully according to the text.
she reaches the end of her list, and the music (led by Mengelberg) slows to a standstill, and falls completely silent...
In most recordings, the singer simply continues without a break into the final, conclusive, line.
'sonst hat mein Jesus nichts getan' (my Jesus has done nothing else) —
reinforcing the point that all the accusations made against him before Pilate are false.
But in that last line, there is first that endless silence where she gathers her emotions.
In one tiny arioso, musical, dramaturgical and theological insight of singer and conductor combine to produce astounding beauty and truth with notes that were written 200 years earlier.
